ET BEEP at www.encodeteam.com
Nice free tray alarm that uses internal beeper (which is always on so you won't miss it), and has an editor for alien like sounds. |

Cellflow
http://www.xs4all.nl/~westy31/CellFlow/CellFlow.html
This is about CFD (ComputerFluidDynamics). It is a Cellular Automate. It calculates free convection, the sound generating flow in a flute, and so on.
Google "Lattice Boltzmann Method" for theory.
To see free convection animation example(usefull for electronics cooling):
1.Dowmload "Windows Executable file" (=Cellflow.exe) and "2D free convection example" (=Freeconv2.gmt) in the same directory.
2.Run Freecell.exe
3.Click Freecon2.gmt in the lower list box. And click button "Import geometry". Click OK in the pop up box.
4. Click "Cont"
5. Watch the show! A live time developing simulation of flow and temperature. After some time you see interesting oscillations of falling cold pockets.
Using a spreadsheet you can input your own design. You have to use tricks to limit the number of points, otherwise the calculations are extremely time consuming. |

Recently found and liked: http://freerouting.net — a free Java-based PCB routing software. Compatible with Eagle and with whatever can export .dsn files. This is probably the first standalone router that didn't make me angry. It can push away the traces, drag components while keeping them properly connected and all that stuff Eagle can't do.
For a test I re-routed a Nixie daughterboard for one of my clocks using free-angle routing. The straight one is the original, spider-on-caffeine one is FreeRouting-ed.
I was so impressed that I even made a little video, forgive me the horrible quality but it should give the idea about how this happens.

A long time back I recommended people switch to Foxit PDF reader, which at the time provided a much better alternative to (then) Adobe Reader 7. Since then versions 8 and 9 came out which were much faster and cleaner, so I switched back.
However, due to the myriad of security vulnerabilities in it, I've switched away from Adobe once more. Foxit is no longer a fast, bloat-free alternative. Enter Sumatra, a ulta-lightweight PDF reader which renders PDFs perfectly, unlike most other 3rd party readers (including Nitro PDF and Foxit). It's very low-frills, but if you just want to be able to view documents, search through them and jump to the bookmarks it's fantastic.
Ultra small (~3MB), loads in well under a second.

Hi Dean,
Foxit still loads PDFs faster on my system. Sumatra takes much longer to "render" large files. Just thought I'd share my experience, ymmv. |

| Dean! Just tested Sumatra on the AVR instruction set. Works like a charm, loads itself and PDFs lightning fast. Thank you! |

I prefer the free version of the PDF-XChange Viewer. It's an ideal pdf viewer for students. It has a lot of nice pdf commenting features which are more comfortable than those in the free foxit reader and adds no nasty evaluationmarks to an edited pdf.
The print menue has more features and supports "print current view" which lacks the free version of foxit reader.
The current view, single pages or a complete document can be exported as pictures files comfortable, too.
Opening a pdf with the XChange Viewer is not as fast as with the Foxit Reader but it is still reasonable fast.
Regards
Sebastian |

I could never make it do anything usable, even with very simple designs. Tried a few times. |

CodeTyphon, a powerful one click installation package for cross platform native Delphi like RAD/IDE based on Lazarus/FreePascal. CodeTyphon already supports 4 CPU/OS hosts (Win32, Win64, Linux32, Linux64), and 16 CPU/OS targets (arm-Wince, arm-Linux, arm-Embedded, arm-gba, arm-nds, i386-Win32, i386-Linux, i386-FreeBSD, i386-Haiku, x86_64-Win64, x86_64-Linux, x86_64-FreeBSD, powerpc-Linux, powerpc64-Linux, sparc-Linux, sparc-Solaris). More are supported in Lazarus/FreePascal, but others are not yet integrated in CodeTyphon.
